Wintry showers have been lashing the city throughout Saturday afternoon, with hailstones reported falling in isolated showers around the city.

The Met Office say icy patches are expected to form on untreated surfaces during Saturday evening.

The chief forecaster states: “Clear spells after dark will allow temperatures to widely fall below freezing in places leading to the risk of ice on untreated surfaces.

“Meanwhile, further snow showers are expected in western and, more especially, northern parts of this yellow warning area. Over Scotland these showers are likely to produce a further 5-10 cm of snow on areas above 300 m and a few cm to lower levels.”

Organisers for Preston’s Purple Party, which will see Craig Charles and MistaJam DJing on the Flag Market, said the event was still going ahead.

The forecast for Preston currently has clear skies from 7pm with a risk of a wintry showers after 11pm on Saturday.
